To show that ( f(x) = 6x^2 - 24x + 22 ) satisfies the hypotheses of Rolle's theorem on the interval ([0,4]), we need to demonstrate the following:
- The function ( f(x) ) is continuous on ([0,4]).
- The function ( f(x) ) is differentiable on ( (0,4) ).
- ( f(0) = f(4) ).
Let's verify each condition:
-
Since ( f(x) = 6x^2 - 24x + 22 ) is a polynomial function, it is continuous everywhere, including on the interval ([0,4]).
-
( f(x) = 6x^2 - 24x + 22 ) is a polynomial function, which implies it is differentiable everywhere. Therefore, it is differentiable on the interval ( (0,4) ).
-
( f(0) = 22 ) and ( f(4) = 6(4)^2 - 24(4) + 22 = 22 ).
Since all three conditions are satisfied, we can conclude that ( f(x) = 6x^2 - 24x + 22 ) satisfies the hypotheses of Rolle's theorem on the interval ([0,4]).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
